Piaggio Airbox mod

thingiverse

this is a airbox mod for piaggio scooters, it replaces the tube inside the airbox to let air flow more freely -if its too loose you might want to use some glue to fix it in place -performance-wise I saw a noticeable gain in power at low to mid rpm -it is just a tiny bit louder -note that my scooter is far from stock and I use a red malossi air filter, every scooter is different so results may vary for more info on the mod please visit the link below http://modernvespa.com/forum/topic89030?page=1
